connect the clip withthe link that the clip can be removed without disconnecting the link from the adj acent links. I

Astill further obj ect of the invention is to provide interchangeable projecting rollers on the chain which are adapted to be engaged by the teeth of the sprockets.

This invention also consists in certain other features ofconstruction and in the combination and arrangement of the. several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed. out in the appended claims.

In describing-the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which V s Figure 1 is a fragmentary top'plan view, showing portions of the chain passing around a horizontally arranged sprocket.

Figure 2 is a sectional view through Figure" links of the chain and the pro ecting portions 1, showing the chain passing over horizontally arranged sprockets.

Figure 9. is a view of the chain shown in Figure 8, passing over vertically arranged sprockets.

Figure 10 is a view showing admin and "clip formed integral with each other.

Figure 11 is a sectional View through a link provided with a detachable clip which can be removed without disconnr-ictin thelink from I q s b s the ad acent links and showing portion of the sprocket 1n dotted lines.

Figure 12 is a sectlonal view through the joint between two links, with a roller'carried by the nut of the pivotal bolt.

Referring to Figures 1 to 4, the chain'A is composed of a plurality of links 1, each link being connected with the twoadjacent links by the pivots 2and 3 which are arranged at right angles to each other,-whereby the chain can pass over horizontally and vertically ar ranged sprockets B. The pivot'al bolts carry the rollers 4 which arearranged at one side .of the chain and are adapted to be engaged by the teeth of the sprockets.

Figure 3 shows a roller carried by the head of a bolt so that by removing'the bolt, a new roller can be substituted for a worn one.

Figure 12 shows a roller4 carried by the Each sprocket B is formed with a flange 6 at one side thereof side, the flange and'teeth carrying portion forming a perlphera-l space for receiving the of'the bolts or the nuts which are not engaging the teeth. 1

The clips 8 aredetachably connected with the chain. Figures 1, 2 and 4 showing these clips as'being connected with the bolts 3.

Figures 5, 6 and 7 show the clips 8 connected'with extensions 10 011 thelinks 1 by and the teeth 7 are arran ed at the o osite t9 j screws or'bolts ll, and these figuresalso show the links 1 connected together by a sockete d p link 12 and a tongue carrying link 13 which" are pivotall'y' connected together by a bolt 14:

which is arranged at right angles to the bolts or pins15 which connect the links 12 and 13 with the links 1'. The links l2'are formed with the projections 16 through which the bolts 14 pass so that these projections can be engaged by the teeth of some of the sprockets, the teeth of other sprockets entering the space formedin the links 1 between the bosses at the ends of the links which receive the bolts or pins 15. Thus this arrangement permits the chain to pass over either horizontal or verticalsprockets. In this arrangement,.the clips are fastened to the main links 1" at the sides thereof, instead of by means of some of the pivotal bolts, as in the first form..

Figures 8 and 9 show the main links 1 connected together by a short link 17, each link 17 being pivoted to the two adjacent main links by pivots 18 which are arranged" at right angles to each other. The clipsE are connected with the bolts 19. which pass through holes formed in the main links..-

The nuts are engaged'by the teeth of some of the sprockets and the nuts 21 or the rollers carried thereby, of some of the bolts or pins 18 being engaged by the teeth of the oppositely arranged sprockets. In order to pre vent the clips from turning, their inner portions are provided with beveled tongues 22 for engaging, beveled notches in the links.

Figure 10 shows a link 23 with a clip 2 formed integral therewith.

Figure 11 shows a link 1 with a clip 8" connected with the bolt 19 and nut 20.

From the foregoing it will be seen that the chain, with. the links arranged as specified, can readily pass over both the horizontally and vertically arranged sprockets of the ma.- chine and that the clips can be removed from theworn links and attached to the substitute links or vice versa, and by providing the rollers on the tooth engaging parts of the chain, friction will be reduced to the minimum.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to beunderstood. that changes may be.

made in the construction and in the combination and arrangement of the s'everalparts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A chain'adapted to be engaged by the teethof vertically and horizontally disposed 1 chain, each unit comprising vertically and.

horizontally pivoted rollers which respectively are adapted to be engaged by consecutive teeth of said horizontally and vertically disposed sprockets, verticallyand horizontally pivoted hinges upon each of said units, and tentering clips pivoted onto said chain in fulcrums arranged transversely to said chain.

3. In combination with a universally jointed chain of the kind described, members extending from adjoining sides of said chain, horizontally disposed sprockets, the teeth of whichare adapted to engage uponsaidmem; bers extending from one side of said chain,

faces upon said horizontally disposed sprockets' adapted to support. sides of said chain opposite to said side from whichextend the membersada'pt'ed to be engaged by the teeth of said horizontally disposed sprockets, and

tentering members radially extending in a tend some of said members.

5. In combination with a universally jointed chain, two sets of meansright angularly disposed on said chain andlongitudinally offset in respect to each other, each of said the teeth, of a sprocket, and, tentering clips, laterally extending from said. chain.

6.. In combination with a universally jointed chain, two sets of means right angularly disposed on said chain in respect to each studs'of said set- Signed at Passaic, in the countyof Passaic and State of New Jersey, this 17th day of April, A. D. 1929.
